After a certain point, if you complete a line that separates problems, it will not advance unless you use a skip. Also, how are you supposed to answer 2/6 in decimal form?

Seems to miss some basic math.. 5-5*5 really is -20 :P

Bug in the game: sometimes it gives you a blank question and if you hit return it counts the answer as correct giving you extra time. It won't advance unless you skip the blank "question".

Shinhidora: They don't make it clear, but you're supposed to solve the problems using PEMDAS, not going left to right. So for example, 5-5*5 = 5-25 = -20.
